Question

Explain Methods of writing electronic configuration.

Answer 1

Hund's rule:- It states that the pairing of the electrons does not takes place in the orbitals of a particular sub shells (s,p,d) untill all the orbitals of sub shells first singly occupied. Moreover the singly occupied orbitals must contain the electrons with the opposite spins.

Electronic configuration varies from element to element

For example the electronic configuration of aluminum is 3s23p1.

Answer 2

Step-by-step explanation:

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. ... This is also useful for describing the chemical bonds that hold atoms together.
